My ZD1100 is running 9.8.0.0 build 373. I have been trying to upgrade it to 9.8.2.0.15 and it always fails on "insufficient memory" error. I followed KB article 1689 without success.
i don't remember what versions i tried and wich version was working. but i'm sure i was managing it with another browser. may be also try with a different OS.
